Introduction

Many millions of trees are planted every year in Australia. The trees help to remove and store the greenhouse gas called carbon dioxide. Revegetation is more than just planting trees. It includes:

Replanting an ecosystem, with trees shrubs, grasses, creepers and wildflowers. This kind of planting will create homes for many animals and help restore the biodiversity in an area.

Restoring an area by removing weeds from around the indigenous plants and planting more local plants among the gaps.

Using the local indigenous plants. The seeds and cuttings used to propagate the plants come from local areas whenever it is possible.

Maintaining the area to keep it free from weeds and other problems after an area has been planted.

Consult your local indigenous nursery - getting their help is a great way to find out specific information. The indigenous nursery will need to know what kind of ecosystem you want to establish and this will guide the choice of plants.
